SDCL1005C2N2BTDF 为顺络(Sunlord)出品的0402(公制1005)贴片叠层电感,标称电感量 2.2 nH,直流电阻(DCR)200 mΩ,额定直流电流 300 mA,品质因数 Q = 8(@100 MHz),自谐振频率(SRF)约 6 GHz。该器件体积小、频带宽、适用于对尺寸和高频特性有要求的移动终端、射频前端及高密度混合信号电路。
在低于自谐振频率的工作区间,器件表现为感性,阻抗随频率线性上升(Z ≈ jωL),适合用作射频匹配、偏置电感或串联阻抗元件。Q 值 8@100 MHz 表示在中高频段存在一定损耗,DCR 相对偏高,意味着在低频直流通流时会产生较大的 I^2R 损耗。SRF 6 GHz 提示在 GHz 级别仍可保有感性特性,但靠近 SRF 时相位与阻抗特性将发生明显变化,超过 SRF 后呈容性行为。
0402 小封装要求在 PCB 走线与焊盘设计中控制焊接热量与机械应力。推荐采用标准 0402 阶梯焊盘并遵循厂商推荐回流曲线;避免过长的回流高温或多次回流导致性能漂移或焊接失效。安装时保证走线短且对称,以降低寄生电容与串扰。
建议在量产前进行温升测试、回流焊耐受性测试和频率特性验证(Z、Q、SRF、S11/S21)。确认在目标工况(温度、频率、偏置)下性能稳定且满足 EMI/EMC 要求。
SDCL1005C2N2BTDF 以其小尺寸和较高自谐振频率,适合用于对板级空间和高频响应有要求的射频与高频电路。选型时需综合考虑 DCR、额定电流与实际工作频段,通过实验验证器件在目标电路中的真实表现,以获得最佳的电气与热可靠性。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
